Hypothesis & Statistics
H0 (null hypothesis) Gender role perceptions of restaurant guests have no effect on decisions to reward or punish restaurant wait staff personnel who draw happy faces on guest checks.H1(alternative hypothesis) Restaurant guest with traditional gender role perceptions will reward female wait staff and punish male wait staff who draw happy faces on guest checks.Such a study would be difficult to conduct because it would be necessary to measure the gender role perceptions of a relatively large sample of restaurant guests using a measurement instrument that provides valid and reliable differentiations between
The advent of reliable and well designed statistical software packages that calculate the precise probabilities associated with variable distributions and relationships replaced probability tables because the use of such tables provide the following advantages:Probability estimates that are more precise than are those attained through the use of probability tablesProbability estimates that are less susceptible to error than are those attained through the use of probability tablesProbability estimates that are determined much more quickly than are those attained through the use of probability tablesProbabilities are relatively easy to calculate when one is considering coin flips, dice throwing, are drawing cards. Calculating probabilities can become an insanely complex and tiresome process when one is working with large and complex data sets. people with strong or week perceptions of traditional gender roles. Such confounding variable might include the following: Restaurant type (upscale, slop house, and so forth)The effects on rewards to wait staff personnel of the use of ingratiating behaviors other than drawing happy faces (other actions by wait staff personnel might offset guest attitudes toward the drawing of happy faces)Q#2Probability table are based on calculations by the developers of the tables. Probability equations are relatively straightforward when one considers the basic equations. It is less likely that probability tables will change over time because the underlying mathematical models are determined to be incorrect; however, because mathematics is a living science such revisions may occur over time. The study also would be complex because it would be necessary to control for the effects of several variables that have the potential to confound the relationship between gender role perceptions of guests, the general of wait staff personnel, and the use of happy face drawings. As such, published probability tables may change over time when (a) errors are corrected or (b) as calculation precision improves. They become daunting as the data become more complex and comprehensive.
